The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
Egg-laying females of this species were the most noticeable insect over the water at dusk on this small trout stream in Wisconsin's Blue Hills. I caught several of them and photographed one, but this was the only male, netted in mid-air mated to one of the females.
This mayfly was collected from Devil's Creek in Wisconsin on June 14th, 2021 and added to Troutnut.com by Troutnut on June 21st, 2021.
